. , the fastest update after wearing the book, she became the latest chapter of a big farmer!

The question in the workbook is to calculate what 1+2+3+4+......+10 is equal to in a simple way, which is still an additional problem.

The three monkeys scratched their ears and cheeks, and they had no clue at all.

After all, he is only an eight-year-old child now, and he has only been in school for two years.

The New Year's painting is happy when I see this topic, isn't this Gauss's theorem?

In the original era of New Year's paintings, anyone who went to elementary school should know this theorem. But in this era, this question can stump the three monkeys and Liang Yin.

Liang Yin's superficial knowledge really can't solve such a problem, according to their method, they can only add it one by one.

The three monkeys are calculated by adding in the book, and it is calculated to be equal to 55.

But it's not an easy way!

Liang Yin had nothing to do, so he could only pouted and said, "Just do it, it's an additional question anyway, and it doesn't matter if you answer it wrong." ”

"Three monkeys, I know how to answer this question."

Seeing that Liang Yin had nothing to do, the New Year's painting was so happy that he reminded softly on the side.

Let you two just look down on me!

Hearing this, Liang Yin didn't believe it at all, and urged Nian Hua to go back to the room to sleep, don't delay the three monkeys to study.

But the three monkeys grabbed the New Year's painting: "Sister, do you really know how to answer?" ”

The New Year's painting nodded, a little tsundere, but in the eyes of the three monkeys, it was a little unfathomable.

"Sister, I believe in you." The three monkeys looked very convinced one second, and the next second, they changed their words. "But if you can't answer, you'll cook a ball for me tomorrow!" And sauerkraut fish! ”

yes, what a clever little ghost, and he actually took the opportunity to make a request.

After thinking about it, she agreed, and she decided to train the sister and brother step by step to become her die-hard fans, and immediately made a request.

"If I answer, you'll have to grant me a request."

"What's the matter?"

"I haven't thought about it yet, I'll tell you if I've thought about it!"

The three monkeys also readily agreed to the New Year's painting, he was clever, knowing that the New Year's painting had not gone to school, and he would definitely not be able to answer such a difficult question.

The thought of the sauerkraut fish he had eaten before made him want to drool.

An agreement was reached between the two sides, and the formal teaching of New Year's paintings began.

Pointing to the title, she asked, "What is 1+10?" ”

The three monkeys did not hesitate: "11. ”

"What about 2+9?"

"It's 11 too."

“3+8？”

“11。”

Before the New Year's painting could ask again, the three monkeys suddenly said excitedly: "I know." ”

Liang Yin was still confused: "What do you know?" ”

The three monkeys continued to write in the notebook, saying as they wrote: "4+7 is also equal to 11, 5+6 is also equal to 11, then all of them add up, which is 5 11s, and 5 11s add up to 55." ”

Hearing the three monkeys explain the method, the New Year's painting nodded secretly. The three monkeys are really smart, and he can draw inferences from each other after saying two sentences in the New Year's painting, and he can bypass the analogy.

In the future, he will be worthy of being a scholar.

"That's right, that's the way, 5 times 11 is 55."

As soon as the two sides explained this, Liang Yin also understood.

It's actually a method like this, and it's really much easier than addition.

But the question is, didn't she go to school for New Year's paintings, how did she know how to do this?

Liang Yin looked at the New Year's painting, with a puzzled face, she couldn't figure it out about this matter.

"Sister, you're too powerful!"

The three monkeys happily hugged the New Year's painting, looking at her eyes with great admiration, and they can make delicious food, and even additional questions can be made, his little sister-in-law is simply amazing!
